What is Allyl methacrylate?
Allyl methacrylate (CAS 96-05-9), abbreviated AMA and sold as Ageflex AMA, is a bifunctional monomer with two distinct polymerizable groups.
Where is Allyl methacrylate used?
- Coatings: cross-link density for hardness, chemical resistance and adhesion to metals and plastics
- Adhesives and sealants: tunes cohesive strength and flexibility in acrylic and methacrylate systems
- Electronics: photoresists and encapsulant resins where cross-link architecture governs pattern resolution and dielectric stability
- Plastics and polymer compounding: reactive modifier that compatibilizes blends or grafts functional groups onto polymer backbones
- In polymer synthesis it acts as a cross-linking agent controlling network density and cure response.
Good to know: Typically inhibited with hydroquinone monomethyl ether to prevent premature polymerization during storage and transport.
Commercial specifications
- Purity commonly 98% or higher
- Packaging from drum quantities to ISO tank
